rAAV-based and intraprostatically delivered miR-34a therapeutics for efficient inhibition of prostate cancer progression.
Article in Gene therapy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
At present, there is no effective treatment for prostate cancer (PCa). Previous studies have reported that miR-34a is significantly downregulated in PCa cells; therefore, modulation of miR-34a expression might be a promising therapeutic approach for PCa treatment. To this end, we first verified the downregulation of miR-34a in prostate tumors from a transgenic adenocarcinoma mouse prostate (TRAMP) model. We found that miR-34a overexpression significantly inhibited the cell cycle, viability, and migration of PCa cells by targeting its downstream genes. Next, we tested the concept of intraprostatic injection of rAAV9·pri-miR-34a into 8-week-old TRAMP mice to inhibit PCa progression. We observed that the treatment lowered body weights significantly compared to the control treatment starting at 30 weeks after injection. rAAV9·pri-miR-34a treatment also obviously extended the lifespan of TRAMP mice. Moreover, we confirmed that the neoplasia in the treated prostates was significantly diminished compared to that in the control group. In addition, overexpressed miR-34a downregulated the expression of its target genes. Taken together, our results demonstrated, for the first time, the potential of rAAV-mediated efficient modulation of miR-34a expression in the prostate to inhibit PCa progression by regulating its downstream gene expression.
